What it is
The Biasi BI2045103 is an earth wiring assembly used in Biasi gas boilers. It provides the earth connection between the appliance's electrical components and the boiler chassis. The part is listed by the manufacturer as a wiring item within the boiler's electrical harness.
Signs this part needs replacing
- Boiler locks out or fails to sense flame intermittently, pointing to a broken earth path
- Visible fraying, cracking or heat damage to the cable insulation
- Loose, corroded or discoloured spade terminals that will not sit tight
- Continuity to earth cannot be confirmed with a meter during service
- RCD or earth leakage trips traced to the boiler wiring
Before you order
- Confirm your boiler model and GC number against the fitment list above
- Inspect the existing earth lead and its terminals to confirm the same connector arrangement and routing
- Isolate the electrical supply to the boiler before carrying out any inspection or replacement work
- Check that the fault lies with the earth lead itself and not with the component it connects to
